A self contained ultrasonic bucket water level sensor so that you don't forget to empty your condensation water bucket before it overflows.
Fully self contained, automatic start and stop when placed on the side of the bucket, auditory and visual alarm when triggered. Visual cue for normal operation (led blinks every 10 seconds or so)
